Golden Oozaru
From Multiversal Omnipedia
The Golden Oozaru is a form of Oozaru attained when the Saiyan in question has previously attained the Super Saiyan state. Aside from being radically more powerful than a conventional Oozaru, there is little difference from the "common" form.

It has been theorized that the Legendary Super Saiyan attained this form before he destroyed himself.
